A quick post on linear algebra: moar linear algebra

Here I am again, learning some more of this.

I started a book and watched a video.

I guess that I could read the book on the bus.

And on the train to London when I go.

Matrices

A matrix is a quantity with m rows and n columns of data.

"We can combine multiple vectors into a matrix where each column of that matrix is one of the vectors".

THE MATRIX - AGAIN

"WE CAN ALSO THINK OF VECTORS AS SINGLE-COLUMN MATRICES IN THEIR OWN RIGHT."

WE CAN ALSO THINK OF VECTORS AS SINGLE-COLUMN MATRICES IN THEIR OWN RIGHT. WE CAN ALSO THINK OF VECTORS AS SINGLE COLUMN MATRICES IN THEIR OWN RIGHT.

MATRICES ARE HELPFUL BECAUSE THEY ALLOW US TO PERFORM OPERATIONS ON LARGE AMOUNTS OF DATA, SUCH AS REPRESENTING ENTIRE SYSTEMS OF EQUATIONS IN A SINGLE MATRIX QUANTITY.

THE SHAPE OF A MATRIX IS ALSO SAID TO BE MXN, WHERE THERE ARE M ROWS AND N COLUMNS.

WHEN REPRESENTING MATRICES AS A VARIABLE, WE DENOT THE MATRIX WITH A VAPITAL LETTER AND A PARTICULAR MATRIX ELEMENT AS THE MATRIX VARIABLE WITH AN "M,N" DETERMINED BY THE ELEMENTS LOCATION.

WHAT HUH?

EH?

OH RIGHT YES I SEE

The answer of course being F.
